Purpose of the Part

The 3915176C91 gives the driver direct control of the truck's signaling functions from the steering column. Because several controls are combined in the same assembly, a problem inside the switch can affect more than one function even when the lights, wiper motor, or other downstream components are still working normally.

Issue Symptoms / When to Replace

A worn switch may cause turn signals that work intermittently, fail to stay engaged, or stop responding from one side of the lever. Other signs can include a hazard switch that does not respond or intermittent wiper, washer, or dimmer operation on configurations where those functions pass through the same switch. Wiring, fuses, relays, and lighting components can create similar symptoms, so the switch should be diagnosed before replacement.
